Claims

[Scope of utility model registration request]

A plurality of pantograph members are intersected in an X-shape and connected in the left-right direction, and the central intersecting position of the pantograph member and the end intersecting position of the adjacent pantograph member are connected to the main vertical frame and the auxiliary vertical frame to form a door body. In the telescopic gate door, in which one side of the door body is rotatably suspended from a fixed post via a hinge mechanism, the pantograph member attached to the lower part of the door body has an end intersection position below the adjacent pantograph members. A pin shaft for pivotal connection projects front and rear outwards and is fixed to the main vertical frame, and a pin shaft for pivotally connecting the center crossing position of the pantograph member projects front and rear outward and fixed to the auxiliary vertical frame, and is fixed to the auxiliary vertical frame as appropriate. An engagement tool equipped with a drop bar is provided at the lower part of the main vertical frame in a vertically movable manner, and is attached to the lower part of the auxiliary vertical frame adjacent to the opening side of the main vertical frame when the door body is retracted. The present invention is characterized in that an engaging protrusion that abuts the engaging tool is provided, the drop bar is fitted into the guide rail when the door body is extended, and the drop bar is detached from the guide rail when the door body is retracted. Drop rod device for telescopic gates.
